Description

本発明は、固体絶縁開閉装置に関する。特に、固体絶縁開閉装置の極柱構造に関する。   The present invention relates to a solid insulated switchgear. In particular, the present invention relates to a pole post structure of a solid insulated switchgear.

従来技術に係る固体絶縁開閉装置は、高圧充電部が絶縁樹脂でモールドされた真空インタラプタ(VI)と真空インタラプタの開閉動作を行う操作機構等が台車上に備えられた可動部と、母線、接地装置およびケーブル接続部等が設けられた固定部を備える。可動部を固定部に取り付けまたは取り外すことで、可動部側の断路部と固定部側の電力ケーブルの着脱や、可動部側の断路部と固定部側の母線の着脱が行われる。   The solid insulated switchgear according to the prior art includes a movable part provided on a carriage with a vacuum interrupter (VI) in which a high voltage charging part is molded of insulating resin and an operating mechanism for opening and closing the vacuum interrupter, a bus bar, and grounding It has a fixed part provided with an apparatus and a cable connection part etc. By attaching or detaching the movable part to the fixed part, attachment and detachment of the disconnecting part on the movable part side and the power cable on the stationary part side and attachment and detachment of the generatrix on the movable part side and the disconnected part and the stationary part side are performed.

図6に示すように、固体絶縁開閉装置19の可動部には、真空インタラプタ20と、真空インタラプタ20の開閉動作を行う操作機構21と、主回路導体22が備えられる。   As shown in FIG. 6, the movable portion of the solid insulated switching device 19 is provided with a vacuum interrupter 20, an operation mechanism 21 for opening and closing the vacuum interrupter 20, and a main circuit conductor 22.

真空インタラプタ20の可動リード20aには、リングコンタクト23が備えられ、リングコンタクト23は、コンタクトケース24に収納される。可動リード20aの端部には、変換レバー25(三角レバー)がピン結合されており、可動リード20aは、変換レバー25および絶縁ロッド26を介して操作機構21に連結される。変換レバー25は、コンタクトケース24内に取り付けられる。主回路導体22の上端部は、真空インタラプタ20の可動リード20aとリングコンタクト23、27を介して電気的に接続され、主回路導体22の下端部は、下部断路部28を介して固定部側の母線(図示せず)に接続される。また、真空インタラプタ20の上端面(固定側フランジ面)には上部導体29が配置され、上部導体29は固定リード20bにボルト締めにより固定される。上部導体29は、上部断路部30を介して固定部側の電力ケーブル(図示せず)に接続される。   The movable lead 20 a of the vacuum interrupter 20 is provided with a ring contact 23, and the ring contact 23 is accommodated in the contact case 24. A conversion lever 25 (triangular lever) is pin-connected to an end of the movable lead 20 a, and the movable lead 20 a is coupled to the operation mechanism 21 via the conversion lever 25 and the insulating rod 26. The conversion lever 25 is mounted in the contact case 24. The upper end portion of the main circuit conductor 22 is electrically connected to the movable lead 20a of the vacuum interrupter 20 through the ring contacts 23 and 27, and the lower end portion of the main circuit conductor 22 is fixed to the fixed portion side via the lower disconnecting portion 28 Connected to a bus (not shown) of Further, the upper conductor 29 is disposed on the upper end surface (fixed side flange surface) of the vacuum interrupter 20, and the upper conductor 29 is fixed to the fixed lead 20b by bolting. The upper conductor 29 is connected to the fixed part side power cable (not shown) via the upper disconnecting part 30.

真空インタラプタ20が閉路状態で、図示省略の保護制御装置から操作機構21に開路命令が出ると、操作機構21が絶縁ロッド26を軸方向に引っ張り、変換レバー25が回動する。変換レバー25の回動により、真空インタラプタ20の可動リード20aが下方に引っ張られ、真空インタラプタ20の電極が開き、真空インタラプタ20が開路状態となる。また、真空インタラプタ20の開路状態で、図示省略の保護制御装置から操作機構21に閉路指令が出ると、操作機構21が絶縁ロッド26を軸方向に押し出すことで、真空インタラプタ20の可動リード20aが上方に押し出され、真空インタラプタ20の電極が閉じ、真空インタラプタ20が閉路状態となる。   When the vacuum interrupter 20 is in a closed state and an open circuit instruction is issued from the protection control device (not shown) to the operating mechanism 21, the operating mechanism 21 axially pulls the insulating rod 26 to rotate the conversion lever 25. The movable lead 20a of the vacuum interrupter 20 is pulled downward by the rotation of the conversion lever 25, the electrodes of the vacuum interrupter 20 are opened, and the vacuum interrupter 20 is opened. Further, when a close command is issued from the protection control device (not shown) to the operating mechanism 21 in the open state of the vacuum interrupter 20, the operating mechanism 21 pushes the insulating rod 26 axially to move the movable lead 20a of the vacuum interrupter 20. It is pushed upward, the electrode of the vacuum interrupter 20 is closed, and the vacuum interrupter 20 is closed.

本発明の実施形態に係る固体絶縁開閉装置について、図面に基づいて詳細に説明する。   A solid insulated switchgear according to an embodiment of the present invention will be described in detail based on the drawings.

図1に示すように、本発明の実施形態に係る固体絶縁開閉装置1は、真空インタラプタ2(VI)と真空インタラプタ2の開閉動作を行う操作機構3等が台車4上に備えられた可動部5と、図示していない、母線、接地装置およびケーブル接続部等が設けられた固定部を備える。可動部5を固定部に取り付けまたは取り外すことで、可動部5側の上部(ケーブル側)断路部6と固定部側の電力ケーブル(図示せず)の着脱や、可動部5側の下部(母線側)断路部7と固定部側の母線(図示せず)の着脱が行われる。   As shown in FIG. 1, the solid insulated switching device 1 according to the embodiment of the present invention includes a movable portion provided on a carriage 4 with an operating mechanism 3 and the like for opening and closing the vacuum interrupter 2 (VI) and the vacuum interrupter 2. 5 and a fixed portion (not shown) provided with a bus bar, a grounding device, a cable connection portion and the like. By attaching or detaching the movable part 5 to the fixed part, the upper (cable side) disconnecting part 6 on the movable part 5 side and the power cable (not shown) on the fixed part side are attached or detached, or the lower part of the movable part 5 (bus bar) Side) Disconnection between the disconnecting portion 7 and the busbar (not shown) of the fixed portion is performed.

固体絶縁開閉装置1の可動部5は、真空インタラプタ2、真空インタラプタ2の開閉動作を行う操作機構3および主回路導体8を備える。   The movable portion 5 of the solid insulated switching device 1 includes a vacuum interrupter 2, an operation mechanism 3 for opening and closing the vacuum interrupter 2, and a main circuit conductor 8.

真空インタラプタ2は、可動リード2aの軸が水平方向に移動するように備えられる。例えば、真空インタラプタ2は、可動リード2aの軸が可動部5の移動方向(固定部への取り付け方向または取り外し方向)と平行となるように備えられる。真空インタラプタ2の外周は、シリコンゴム等の絶縁性弾性体9で被覆され、さらにその外周にはエポキシ樹脂等の絶縁樹脂でモールドされたモールド部10が備えられ、モールド部10の表面は接地層(図示せず)で覆われる。   The vacuum interrupter 2 is provided such that the axis of the movable lead 2a moves in the horizontal direction. For example, the vacuum interrupter 2 is provided such that the axis of the movable lead 2a is parallel to the movement direction (attachment direction to the fixed part or removal direction) of the movable part 5. The outer periphery of the vacuum interrupter 2 is covered with an insulating elastic body 9 such as silicone rubber, and the outer periphery thereof is provided with a mold portion 10 molded with an insulating resin such as epoxy resin, and the surface of the mold portion 10 is a ground layer Covered (not shown).

真空インタラプタ2の固定側フランジ面には、固定側導体11が設けられる。固定側導体11は、ボルト締め等により真空インタラプタ2の固定リード2bに固定される。固定側導体11は、上部断路部6を介して固定部側の電力ケーブル(図示せず)に接続される。   The stationary side conductor 11 is provided on the stationary side flange surface of the vacuum interrupter 2. The fixed side conductor 11 is fixed to the fixed lead 2b of the vacuum interrupter 2 by bolting or the like. The fixed side conductor 11 is connected to a power cable (not shown) on the fixed portion side via the upper disconnecting portion 6.

可動リード2aには、可撓導体12(フレキシブル導体)が設けられる。また、可動リード2aの端部には、絶縁ロッド13を介して操作機構3が連結される。可撓導体12は、可動リード2aと主回路導体8を接続する接続導体である。可撓導体12は、例えば、薄い銅板を重ね合わせた板状の導体である。   The movable lead 2a is provided with a flexible conductor 12 (flexible conductor). Further, the operation mechanism 3 is coupled to the end of the movable lead 2 a via the insulating rod 13. The flexible conductor 12 is a connection conductor that connects the movable lead 2 a and the main circuit conductor 8. The flexible conductor 12 is, for example, a plate-like conductor in which thin copper plates are stacked.

図2に示すように、可撓導体12の一端は、絶縁ロッド13の端部に設けられたスタッドボルト14により、可動リード2aに固定される。可撓導体12の他端は、可動リード2aの下方に延在し、可撓導体12の下端部が水平方向に折り曲げられる。そして、可撓導体12の折り曲げられた下端面が主回路導体8の上端面に接した状態で、可撓導体12の下端部が主回路導体8の端部にボルト15等で固定される。   As shown in FIG. 2, one end of the flexible conductor 12 is fixed to the movable lead 2 a by a stud bolt 14 provided at the end of the insulating rod 13. The other end of the flexible conductor 12 extends below the movable lead 2a, and the lower end of the flexible conductor 12 is bent in the horizontal direction. Then, the lower end portion of the flexible conductor 12 is fixed to the end portion of the main circuit conductor 8 with a bolt 15 or the like in a state where the bent lower end surface of the flexible conductor 12 is in contact with the upper end surface of the main circuit conductor 8.

主回路導体8の上端部は、モールド部10に嵌め込んで備えられる。モールド部10には、主回路導体8の上端部が備えられる孔10aが形成される。孔10aの開口端近傍であって、主回路導体8の上端部とモールド部10との間には、防水のためのパッキン16が備えられる。また、モールド部10には、主回路導体8の上端部が摺接する支持部10bがモールド部10と一体に形成される。支持部10bは、例えば、主回路導体8の側面が摺接可能な孔状に形成され、支持部10bを挿通して、主回路導体8の上端部がモールド部10に設けられる。そして、主回路導体8の上端面に可撓導体12がボルト15で固定され、主回路導体8と可撓導体12(および可動リード2a)が電気的に接続される。また、主回路導体8の下端部は、下部断路部7を介して固定部側の母線(図示せず)に接続される。   The upper end portion of the main circuit conductor 8 is fitted in the mold portion 10 and provided. The mold portion 10 is formed with a hole 10 a in which the upper end portion of the main circuit conductor 8 is provided. A gasket 16 for waterproofing is provided in the vicinity of the opening end of the hole 10 a and between the upper end portion of the main circuit conductor 8 and the mold portion 10. Further, in the mold portion 10, a support portion 10b in sliding contact with the upper end portion of the main circuit conductor 8 is integrally formed with the mold portion 10. For example, the support portion 10 b is formed in a hole shape in which the side surface of the main circuit conductor 8 can be in sliding contact, and the upper end portion of the main circuit conductor 8 is provided in the mold portion 10 through the support portion 10 b. Then, the flexible conductor 12 is fixed to the upper end surface of the main circuit conductor 8 with a bolt 15, and the main circuit conductor 8 and the flexible conductor 12 (and the movable lead 2a) are electrically connected. Further, the lower end portion of the main circuit conductor 8 is connected to a bus bar (not shown) on the fixed portion side via the lower disconnecting portion 7.

真空インタラプタ2が閉路状態で、図示省略の保護制御装置から操作機構3に開路指令が出ると、操作機構3が絶縁ロッド13を介して可動リード2aを引っ張ることで、真空インタラプタ2の電極が開き、真空インタラプタ2が開路状態となる(図2(a)参照)。このとき、可動リード2aと主回路導体8は、可撓導体12で接続されているため、可撓導体12が変形して可動リード2aと主回路導体8の通電が確保される。また、真空インタラプタ2が開路状態で、図示省略の保護制御装置から操作機構3に閉路指令が出ると、操作機構3が絶縁ロッド13を介して可動リード2aを軸方向(真空インタラプタ2方向)に押し出すことで、真空インタラプタ2の電極が閉じ、真空インタラプタ2が閉路状態となる(図2(b)参照)。   When an open circuit command is issued from the protection control device (not shown) to the operating mechanism 3 while the vacuum interrupter 2 is in a closed state, the operating mechanism 3 pulls the movable lead 2 a through the insulating rod 13 to open the electrodes of the vacuum interrupter 2. The vacuum interrupter 2 is in the open state (see FIG. 2A). At this time, since the movable lead 2a and the main circuit conductor 8 are connected by the flexible conductor 12, the flexible conductor 12 is deformed to ensure that the movable lead 2a and the main circuit conductor 8 are energized. Also, when the vacuum interrupter 2 is in the open state and a command to close the circuit is issued from the protection control device (not shown) to the operating mechanism 3, the operating mechanism 3 moves the movable lead 2 a in the axial direction (vacuum interrupter 2 direction) through the insulating rod 13. By pushing out, the electrode of the vacuum interrupter 2 is closed, and the vacuum interrupter 2 is in a closed state (see FIG. 2 (b)).

以上のような、本発明の実施形態に係る固体絶縁開閉装置1によれば、可動リード2aの軸の移動方向が水平方向となるように真空インタラプタ2を配置(つまり、横向きに真空インタラプタ2を配置)することで、従来の固体絶縁開閉装置19で使用していた変換レバー25が不要になる(図6参照)。その結果、固体絶縁開閉装置1の極柱が小型化され、固体絶縁開閉装置1を小型化することができる。   As described above, according to the solid insulated switching device 1 according to the embodiment of the present invention, the vacuum interrupter 2 is disposed such that the moving direction of the axis of the movable lead 2a is horizontal (in other words, the vacuum interrupter 2 is horizontally oriented). By the arrangement, the conversion lever 25 used in the conventional solid insulated switchgear 19 becomes unnecessary (see FIG. 6). As a result, the pole post of the solid insulated switching device 1 can be miniaturized, and the solid insulated switching device 1 can be miniaturized.

また、主回路導体8と可動リード2aの接続を可撓導体12で接続することで、従来の固体絶縁開閉装置19のようにリングコンタクト23、27やリングコンタクト23、27を収納するためのコンタクトケース24が不要となる(図6参照)。その結果、固体絶縁開閉装置1を小型化することができる。   Further, by connecting the main circuit conductor 8 and the movable lead 2a with the flexible conductor 12, a contact for housing the ring contacts 23, 27 and the ring contacts 23, 27 as in the conventional solid insulated switchgear 19. Case 24 becomes unnecessary (refer FIG. 6). As a result, the solid insulated switching device 1 can be miniaturized.

また、主回路導体8は、可撓導体12と連結されているものの、主回路導体8の上端部は、固定されていない状態でモールド部10に設けられている。そこで、真空インタラプタ2側のモールド部10(具体的には、モールド部10に形成された支持部10b)で主回路導体8の端部(導体部)を支持することで、通電の電磁力による主回路導体8の上端部の振れを防止することができる。また、真空インタラプタ2に設けられたモールド部10に支持部10bを形成することにより、主回路導体8の振れ防止対策のための専用部品が不要となる。   Further, although the main circuit conductor 8 is connected to the flexible conductor 12, the upper end portion of the main circuit conductor 8 is provided in the mold portion 10 in a state where it is not fixed. Therefore, by supporting the end portion (conductor portion) of the main circuit conductor 8 with the mold portion 10 on the vacuum interrupter 2 side (specifically, the support portion 10b formed on the mold portion 10), the electromagnetic force of the energization is Swing of the upper end portion of the main circuit conductor 8 can be prevented. Further, by forming the support portion 10 b in the mold portion 10 provided in the vacuum interrupter 2, a dedicated part for anti-vibration measures of the main circuit conductor 8 becomes unnecessary.

なお、図3に示すように、モールド部10の主回路導体8が嵌め込まれる孔10aに、主回路導体8の上端部側面を支持する支持部10cを形成し、この支持部10cで主回路導体8のモールド部8aを支持して、主回路導体8の振れを防止することもできる。   In addition, as shown in FIG. 3, the support part 10c which supports the upper end part side surface of the main circuit conductor 8 is formed in the hole 10a where the main circuit conductor 8 of the mold part 10 is inserted, The main circuit conductor is this support part 10c. By supporting the eight mold portions 8a, deflection of the main circuit conductor 8 can be prevented.

また、図4に示すように、モールド部10に形成された支持部10bと主回路導体8の上端部の間に、絶縁材料で形成された環状の緩衝部材17(例えば、環状のブッシュ)を設けることで、支持部10bと主回路導体8の間の隙間を埋め、緩衝部材17の緩衝作用により主回路導体8の振れをさらに防止することができる。   Further, as shown in FIG. 4, between the support portion 10 b formed in the mold portion 10 and the upper end portion of the main circuit conductor 8, an annular buffer member 17 (for example, an annular bush) formed of an insulating material By providing the gap, the gap between the support portion 10 b and the main circuit conductor 8 can be filled, and the buffer action of the buffer member 17 can further prevent the swing of the main circuit conductor 8.

また、図5に示すように、モールド部10の主回路導体8が嵌め込まれる孔10aの開口端部に、絶縁材料で形成された環状の緩衝部材18を設けることで、モールド部10(または、支持部10c)と主回路導体8のモールド部8aの間の隙間を埋め、緩衝部材18の緩衝作用により、主回路導体8の振れをさらに防止することができる。   Further, as shown in FIG. 5, by providing an annular buffer member 18 formed of an insulating material at the open end of the hole 10a into which the main circuit conductor 8 of the mold portion 10 is fitted, the mold portion 10 (or The gap between the support portion 10c) and the mold portion 8a of the main circuit conductor 8 is filled, and the buffer action of the buffer member 18 can further prevent the swing of the main circuit conductor 8.

以上、具体的な実施形態を示して本発明の固体絶縁開閉装置について説明したが、本発明の固体絶縁開閉装置は、実施形態に限定されるものではなく、その特徴を損なわない範囲で適宜設計変更が可能であり、設計変更されたものも、本発明の技術的範囲に属する。   As mentioned above, although the solid insulated switchgear of the present invention was explained showing the concrete embodiment, the solid insulated switchgear of the present invention is not limited to the embodiment, and appropriately designed in the range which does not impair the feature. Modifications are possible, and modifications of design are also within the technical scope of the present invention.

例えば、図2から図5に示した固体絶縁開閉装置における、主回路導体8の振れ防止構造を組み合わせて、主回路導体8の振れ防止を行うこともできる。   For example, in the solid insulated switchgear shown in FIGS. 2 to 5, the deflection prevention structure of the main circuit conductor 8 can be combined to perform the deflection prevention of the main circuit conductor 8.

また、可撓導体12は、可動リード2aの移動の際に、可動リード2aと主回路導体8の通電を確保できるものであれば、実施形態に限定されるものではない。例えば、可撓導体12は、板状に限定されるものではなく、可撓性を有する導体であればよい。   The flexible conductor 12 is not limited to the embodiment as long as the movable lead 2a and the main circuit conductor 8 can be energized when the movable lead 2a moves. For example, the flexible conductor 12 is not limited to a plate shape, and may be a conductor having flexibility.
